Sounds like a problem with the Hyper Board.

SOURCE: Dark Blotches

This is probably caused by dust, either on the mirror, lens, or possibly inside the light engine. There is a 5" dia hole on the side of the back of the tv where you can take out one screw and take the door off. this is just big enough for you to put your hand through to clean the mirror and lens. Hope this helps.

SOURCE: Green and Blue spots on screen

Sounds like stuck pixels, you really can't fix that. Do some google research if you are curious what a stuck pixel is.

SOURCE: White dots appearing on Samsung TV screen and multipling each day

It seems you might have an issue with the dmd board. Go to the menu, and if the dots still show on the menu, the issue definitely is with the dmd board but if they don't come up on the menu, the issue will be with the video board.

Green screen


1.) Press and hold down the "Menu" key until the manufacturer's logo appears on the screen. This could take up to a minute or more. Release the "Menu" key when the logo appears.
2.) Immediately press the "9," "8," "7" and "6" keys in this order. Press the "Enter" button on the remote to enter the "Service Menu" screen.
3.) Press the "Menu" button to go to the second of the two "Service Menu" screens. Press down on the "Down" arrow until you highlight "Color Calibration." Press the "Enter" button to enter the "Color Calibration" screen.
4.) Select one of the color bars on the screen. Adjust the color by changing the values of the color bar by pressing left and right on the "left" and "right" arrows on the remote. Repeat this procedure with the other color bars as well. Stop adjusting the colors when the green cast is no longer present.
5.) Press and hold the "Power" button on the remote to exit the "Service Menu" and save the adjustments you have made.
Now turn the T.V. off. When you turn it back on it should reflect your personal preference.

Contrast really dark but seems to improve after the tv has been on several hours


Hi:
You may have a problem with the inverters in the unit, they are responsible for lighting up the back panel. Check or have checked the power supply voltage to the inverters, should be around 18-24 volts DC. Also leaky capacitors on the power supply will cause this issue as well as leaky or puffy capacitors on the inverter.

I have a Onkyo TX-SR806 HDMI output does not work anymore. Tried switching HDMI cables. My component video output works.


Sounds like you may have a bad HDMI card my friend. I had an issue with my HDMI card that was causing blue dots to appear on the dark parts of the screen, when outputting 1080p over HDMI. This is a rather common issue, so it wouldn't surprise me if your HDMI board needs replacement - especially if you've ever experienced the infamous blue dot issue.
